I'm currently on 8kz , surely I'll put it on 4kz
For the fix and max timing I should change something?
Thanks for the help.
After seeing the video, you are miles undergeared !

Start again with standard mode 9 and go from there (switchpoint at 12-15000) ensure temp protection is on and set to a sensible value to begin with.

Personally I would gear at somewhere around 6fdr and check the temps after a couple of minutes.

Yes now I have put this mode but the fixed timing is at 30 and the max to 60 maybe is it too much?

Martin, I was looking at your v13-basic gd2 setup and noticed the "variable depence timing" is NOT selected. So when does the timing come in now?

I always have used this as you have mentioned its good several times.

Do a factory reset and start from standard mode 9

Yes I know, but I mean with standard mode 9 there is fixed timing at 30 and the max to 60 .
Is it too much for the motor?
I read that for gm motor the best values are 20-26.

there shouldnt be 30 with standard mode 9.. more like 24 ?

20 is a good starting point for a 10.5 (max timing 21)

No I think it is 30/60 for std mode 9, and for me, yes that is too high for 10.5.

Like Chris says, 20/21 is probably a decent starting point, but I'd say you should generally be ok 24/25 ish - just keep a keen eye on temps.

With HST, you only need to adjust fix timing. So the 30/60 has nothing to do.

Well that's what I'm thinking.

Someone correct me if I'm wrong.

Ok thank you guys, I'll put this set up the next time I go on the track.
Approximately in what range of gear ratio I should stay?

If you have a heavy throttle finger, variable depence timing is good for you as it will smoothen out your acceleration action. It totally changes the feeling of the speedo though and I recently got the impression that people prefer the more linar feeling of not having it ticked.

Yes you are definately undergeared, go for somewhere around 6.0 and leave the timing where it is right now.
Set the motor temperature to 120C for a GM motor and it will limit itself when it gets too hot. Easy. If you feel it gets soft, the speedo protects your motor. Just don't push then but rather keep it smooth.
When the motor has cooled down a little (usually 1-2 laps) you can go for it again.

Sorry: Maxtiming is the power value for launch control (enabled if you don't touch the throttle trigger for more than 5 seconds).
I suggest to use the same value as fixed timing or fixed timing +1

see post above,

around 6.0, same timing, motor temp to 120. if it gets soft, try to keep it smoother.
Enable the switchpoint and set it to around 15000 rpm.

you could actually try to gear somewhere between 5.0 and 5.5, that'S where I would gear atleast, but start with 6.0 and see what it does.

harder gearing on such big tracks keeps the motor temperature down! revs = heat

Hi all,
Does anyone have a setup for a GM75 on a 1S 1/12th modified?
I did get it running pretty well, but the temps say 98degr. C and I think thats a bit much.
Problem is that I cant get the extra timing to start under 5000rpm so I had to disable that to gain power there (running a 5.5) but that causes the esc to get hot I presume.
Also:
1. how do I reset the esc? Searched everywhere but I cant find it.
2. How do I redo the radio setup? I tried changing mode cause I thought this would automatically do the setup again but I have to lower the epa to 65% (!) on throttle and brake for the endpoints to be OK.
3. any word on the when I spin out the car sits still for 2s problem. This is getting annoying.

Thanks.

Quante, I ran a 75 for mod 12th only last week. It kind of depends on what motor you want to run. I prefer to run more motor and not run any timing, so I ran with a 4.0 motor, and in the std mode 2 profile. I don't think you temps are a huge problem, mine ran at 108 and it was no real issue.

Setting the mode does set the radio values, you should always do this with the radio set at 100%, and it should then be fine.
